oFric COMPOSITE MATERIAL Application iea .april e,

llt is the primary object of my invention to provide a composite material in the nature of a fabric adapted for use as artificial leather or like products.

Among the various other objects of my invention are the use of unspun and unwoveii materials, making possible the use of lowpriced materials with a consequent economy in the finished product.-

While my invention is adapted for many uses and may be fabricated in a number of different ways, it is particularly adapted for use as artificial made by the super-posing of layers of material beginning first with alayer such as cotton, on which is disposed a layer such as jute, flax, hair or other fibre, then disposing another layer ofcotton over themass, followed by another layer of jute, flax, hair or other fibre, the two layers of fibrous material being so disposed that the lines of the fibres of the two different layers will intersect. rlhis intersection of fibres lends material strength to the composition.

With the above objects and advantages 1n View, my invention consists in the arrangement, combination and construction of the various parts of my improved composition, as well as the method of making the saine, as described in the specification, claimed in my claims and shown in the accompanying drawings, in which:

Fig. l is a top o r plan view of my improved material with parts broken away to show its construction.

Fig. 2 is a sectional view showing the same.

l have shown a section of composite material .composed of a layer of cotton 5, upon which is placed a layer of jute, iiax, hair or other bre 6, with the strands thereof curled, twisted or otherwisel distorted in a manner most easily or usually obtained according to the particular material used. Upon the layer 6 isl super-posed another layer Z of cotton and upon this is placed another layer 8 of fibrous material so disposed that at least some of the strands of the fibre will cross with those in the layer 6. Upon the layer 8 is disposed another layer 9 of cotton. All of the layers are glued or cemented' together leather and is preferably- 1925. Serial No. 21,976.

with rubber or other cement, so as to make a unitary mass and a covering 10 for the top of the material is provided, consisting `of rubber, pyroxyline or linseed oil compositions, or any other well-known combination of materials such as are usually employed in the provision of artificial leather coatings.

The super-posing, or laminating, of the layers of material with the fibres of the fibrous layers intersecting each other provides a strong composition and makes unnecessary the weaving or spinning of the materials. Likewise the use of the fibrous material without necessity of the fibres of each layer being stranded, or otherwise worked (making use of them as they may be found) cheapens the finished product, as does the fact that the grade of material used need not be high. The cotton layers, in particular, need not be of high-grade material, inasmuch as the cotton lends little or no strength to the mass, b ut acts as a filler to give bulk to the composition. l

It will be understood, of course, that as many layers of cotton or-other fillers, and as 'Z5 many layers of jute or other fibrous materials, may be utilized as is desired by the maker to suit the particular need for which the material is to be used i Y It will be obvious that various changes so may be made in the arrangement, combination and construction of the various elements of my invention and in the method utilized in making the same, without departing from the spirit of my invention, and it is my lintention to cover by my claims such changes as may be reasonably included within the scope thereof,

What lf claim is:i

As an article of manufacture a substieo tute for woven covering materials which consists of a pliable mass composed of a plurality of superposed relatively thin layers of unspun and unwoven fibers,having the intervening layers composed of fibers of relatively greater tensile strength than the fibers of the alternate layers, the fibers of each of said intervening layers being disposed in nonparallel and entangling relation to each other and in nonparallel relation to the fibers of ma the other intervening layers, said layers being adhesively secured to each other, and a non-fibrous waterproof cover adhesively secured on one side of said mass.

2. As an article of manufacture a substitute for Woven covering material which consists of a pliable mass composed of a plurality of laminated layers of unspun and un- Woven fibers having the intervening layers Y composed of interlocking fibers of relativel)T greater strength than the fibers of the alternate layers, said layers being adhesively secured to each other, and anon-fibrous substantially Waterproof substance adhesively secured to one side of said mass.

3. As an article'of l'manufacture a substitute for woven covering material which consists of ar pliable mass composed of a plurality of layers of unspun and unwoven fibers, havin the alternate layers composed of occulate cotton fibers, and the intervening layers composed of entangled fibers of relatively greater strength than the cotton fibers, said layers being cemented together, and a substantially Waterproof cover adhesively secured to one side of the mass.

4. As an article of manufacture, a substitute for Woven covering lmaterial which consists of a pliable mass composed of a plurality of laminated layers of unspun and unwoven fibers having posed of interlocking fibers of relatively greater strength than the fibers of other of said layers, said layers being adhesively secured to each other and a substaptially water-proof cover adhesively secured to the mass.
